Secrets / .env

All service API keys and credentials are stored in stacks/media-arr/.env (not committed). An .env.example documents the required keys without values.

Updating Without Resizing rootfs

CT 300's rootfs is 16GB. Docker image updates consume temp space. To update without risking a full disk:

1. Pull a single image at a time:

   docker compose pull <service>
   

2. Stop the old container and start with the new image:

   docker compose up -d <service>
   

3. Prune dangling images after each service:

   docker image prune -f
   

Full docker compose pull + up -d can fill rootfs if multiple large images are pulled simultaneously.

Hardlinks

CT 300 mounts $DATA_ROOT/media → /media and CT 302 mounts $DATA_ROOT/torrents → /torrents and $DATA_ROOT/usenet → /usenet. Because these all come from the same host filesystem ($DATA_ROOT), hardlinks between download categories and media libraries work - one file, two directory entries, zero extra disk space.

Sonarr and Radarr must be configured to use hardlinks (not copy) for imports. Verify with: Settings → Media Management → Use Hardlinks Instead of Copy.
